Luther's Works: The American Edition, published by Concordia and Fortress Press between 1955 and 1986, comprises fifty-five volumes. These are a selection representing only about a third of Luther's works in the Latin and German of the standard Weimar Edition, not including the German Bible.

This volume contains Luther's commentaries on selected psalms beloved by Christians everywhere. They are for the most part the outgrowth of sermons and classroom lectures, family devotions, and private conversations held between 1524 and 1537. Figures of speech, allusions, and references not immediately clear have been carefully explained for a fuller understanding of the text. The archaic literary forms have been removed and obscurities of earlier translations cleared up. This is an updated version of an important piece in Luther's tomes of work seminal to theological consideration everywhere.
